What did the Constitutional Convention aim to address?

The correct choice highlights that the Constitutional Convention, held in 1787, primarily aimed to address the weaknesses of the Articles of Confederation. The Articles, which served as the first constitution of the United States, created a loose confederation of states with a weak central government. This arrangement led to issues such as inability to levy taxes, regulate commerce, and enforce laws. The founders recognized these shortcomings and sought to create a new framework for governance that would allow for a stronger federal authority, while still preserving the rights of individual states.

The other options, such as the Declaration of Independence, taxation policies, and the structure of state governments, are not the primary focus of the Constitutional Convention. While these issues may have been discussed in broader terms, the main goal was to replace the Articles of Confederation with a more effective Constitution that would address the shortcomings of the existing government structure and facilitate a more unified and functional nation.
